Abstract: ABSTRACT     The present invention is directed to a system for use with equipment designed for transmitting a relatively wide-band signal over two or more relatively narrowband circuits so as to provide good overall system reliability even though the  reliability  of the  individual  narrowband  circuits is poor.   If systems,  which transmit  two or more relatively narrowband  circuits to transmit quality greater  than toll circuit quality (approximately 300 hertz to 3,000 hertz), are properly designed,  only a failure of one transmission circuit will severely degrade the transmission of intelli-gible speech. For example, if the system is designed with frequencies between say, 50 hertz and 2,500 hertz, passing through a first transmission circuit and frequencies between 2,500 hertz and 5,000 hertz passing through the second line, there will be little loss of intelligibility if the second transmission  circuit  fails.   However,  loss  of  the  first transmission  circuit  would  be  catastrophic.   The  present invention provides method and means to further improve reli-ability by detecting failures in the operation of the first line and to activate line switching means of both the trans-mitter and the receiver so as to switch transmission of the high intelligibility component of the signal through another line  providing  intelligible  speech  transmission.   The detection of the failure and the activation of the transmit-ter and  receiver  line  switching  circuits  is  designed  to provide rapid corrective measures to avoid serious inter-ruptions of service.  This invention is subject to a wide range of applications, however, it is especially suited for transmission  of  broadcast  programs  from  remote  sites  to broadcast studios.

The sleeve has a plurality of separate fluid pressure chambers progressively arranged longitudinally along the sleeve from a lower portion of the limb to an up-per portion of the limb proximal the patient's heart relative the lower portion.  The device has means for filling the chambers from the source during periodic compression cycles while applying a greater pressure in each lower chamber than the pressure in any upper chamber to apply a compressive pressure gradient against the patient's limb by the sleeve which pro-gressively decreases from the lower to upper limb por-tions.  The device also has means for emptying the chambers during periodic decompression cycles between the compression cycles.

Abstract: (RIFO-11) METHOD OF FABRICATION AND A RESULTING BIREFRINGENT      ELECTROMAGNETIC TRANSMISSION LINE THAT PRESERVES THE      STATE OF POLARIZED RADIATION PROPAGATING THEREIN     ABSTRACT     A method of fabrication and the resulting structure for a birefringent transmission line having particular application as an optical waveguide.  The instant transmission line is fabricated so as to be adapted to maintain the state (e.g. the polarization vector) of polarized electromagnetic radiation propagating therethrough.  Birefringence in the instant transmission line is geometrically generated by producing oblong regions having different indices of refraction through a cross-section of the transmission line.  A preferred technique by which to generate birefringence includes the method step of bombarding the transmission line with a supply of atomic particules, such as energetic hydrogen ions 7 whereby to implant a damaged region of oblong cross-section and thereby cause an internal swelling therein.  By way of a preferred example, the transmission line herein described may be a single-mode optical fiber.

Title: Apparatus for applying elastic ribbon segments to  diapers
Inventor: RADZINS EDMUND
IPC: A61F13/15
Filed: 1981-04-23
Granted: 1983-05-10
Abstract: Abstract of the Disclosure To make diapers having elasticized regions, unstretched segments of elastic ribbon are deposited on a first rotating roll which has vacuum holes in its periphery for attracting the body of a segment and a mechanical element for temporarily securing one end. The first roll rotates segments successively to a place adjacent a second roll which has a larger radius and, hence, higher peripheral velocity than the first roll.  The second roll has grippers spaced apart by an amount substantially equal to the desired stretched length of the segments.  The leading end of each segment on the first roll is engaged by a gripper on the second higher speed roll so the segment stretches after which a lifter on the first roll releases the training end for it to be engaged by a gripper to hold the stretched segment on the second roll.  Quick setting glue is applied to the stretched segments and the top porous sheet material comprising the diaper is run in contact with the segments to pick them up. The exposed faces of the segments have glue applied and the sheet is superposed on a moving non-porous backing sheet on which absorbent pads have been deposited and a continuous diaper web is formed.  The web is cut transversely and remotely from the segments and individual diapers are formed.

Abstract: ABSTRACT OF THE DISCLOSURE         A blow-molded bellows of a thermoplastic elasto-meric material has a generally cylindrical hollow accordion-type convolution section and ends integral therewith.          The ends has axial protrusions extending outwardly from the central areas of respective ends.  Each protrusion is connected to an adjacent convolution by an integral shoulder which has inwardly concave portions and outwardly convex portions.  The concave portions are adjacent to the parting line, whereas the convex portions are remote from the parting line.  By this feature of the bellows, the outer-most convolutions of the accordion-type convolution section of the bellows can be molded into circumferentially substantially uniform wall thickness to assure improved operability and heat-resistant property of the bellows.

Abstract: Abstract of the Disclosure An apparatus is disclosed for centering one or more magnetic discs on a rotatable spindle.  The apparatus includes a disc-carrying hub having a circumferential collar, a central housing supporting a centering ball, and a diaphragm joining the collar and housing, stiff in the radial direction but allowing axial movement of the centering element with respect to the collar.  The hub is attracted to a rotatable spindle by an annular permanent magnet mounted on the spindle opposite a similarly sized armature mounted on the hub.  A cup formed in the spindle at  its center receives the centering ball and guides it to the center of spindle as the hub is attracted to the spindle.  After the centering ball is seated  in the center of the cup, the diaphragm flexes to allow continued axial movement of the collar to full engagement with the spindle.  A second embodiment of the apparatus is a tool for centering a disc pack on a spindle, wherein shoulder  screws extend through the tool and threadedly engage the spindle, to provide a hub-spindle attract-ive force in lieu of the magnet.
